wmnowsmu Application filed May 22, 1925, Serial No.

Thisv invention relatesto casement win dow' stays and fasteners of the type in which a stay is pivoted to a 'link so as to turn downwardly to a vertical positio nsuchlink 8 being pivoted in a bracket fixed tothe sash so as to turn in a lateral'direction, the stay passingtthrough a bracket fixedto the window frame which it engages at intervals. According hereto, thestay is pivoted to 10 the link in such a waythat ;the end of the stay will project above the link. A1nem-' ber upon the bracket fixed to the window Vgfran' e prevents thestay from rising out of enga ement with the bracket. When the 15 stay i'es parallel to the bracket, this memher will engage'between the endof the stay and the face of the bracket in such a way V that the sash will be -drawn inwardly againstthe frame of the window.

The invention will be illustrated inlthe accompanying drawings, wherein Figure 1, is a side elevation of the stay. Figure 2, is a plan. Figure 3, is an end bracket showing the stay in the position of the dotted lines in Figure 1. l I Figure 4, is a sectional plan on line A-A Figure 3. I

Figure 5, is a side elevation of a modified form of stay. 1 j

Figure 6, is a plan thereof.

Referring to thedrawings, but more particularly to Figures 1' m4, the stay 1 is pivoted, to a link 2 by a pin 3 so that the stay may assume a horizontal position. The link 2is pivoted by a pin 4 to a bracket 5 fixed b screws to the window sash 6 so as to enaiile the stay to turn in a lateral direction. A bracket 7 is fixed to the window frame 8 and the stay and link pass through an opening 9 in the bracket 7. A lever 10 pivoted upon the bracket 7 by a pin llhas a projecting tongue 12 and a depending handle 13. The stay 1 is provided with notches 14 at desired intervals upon its bottom edge, these notches engaging with the edge 15 of the opening 9 and when a notch 14 is in osition the tongue 12 prevents the stay rom rising upwards out of engagement with the bracket. This is illustrated in Figure 5.

It will be noticed by referring to Figures 1 and 2, that the stay projects beyond the pin 3 so as to leave an end 16 which, when the stay is in the horizontal position, lies in the jaws of the link 2, but when the stay is turned to the vertical position this end view of the stay and I WELLINGTON, new zEA'LANn.

16 projects above the link as shown inFigures 1 and 3, thereby enabling "the tongue 1 12 to engage between the end 16 and the lace of the bracket.

Bv referringto Figure 4, it will beseen that the tongue is tapered and'soalso is' theinside faceoi'" the end 16, so that when the tongue is forced between the projecting end 16 and the taceof the. bracket the tongue vwill draw the link "2 through'the brackets7 and tightenfihe sash againstthe frame. The notches 14 are preferably formed at an angle as suggested in Figure.

2, so thatas the sash'swings out radially the notches will be parallel with the edge of the bracket. At the point where the stay is pivoted to the linkthe'stay is cutaway as at 17 so as to enable the stay to pass through the opening 9 in thebracket and when one of the notches therein engages the edge 15 of the bracket the tongue will draw the link2 through the brackets 7 andtighten the'sash against the frame, The notches 1 1 are pretefably formed at an angle as suggested in,

Figure 2, so that asthe "sash swings out radially the notches will the parallel with the edge of the bracket.. At the point where the stay ispivoted to the link the. stay is cut away as at 17 so as to enable the stay to pass'through the opening 9 in the bracket and when one of thenotches therein engages the edge 15 of the bracket the top edge of thestay will remain in alignment withthe top edge of the link 2 and for this purpose the distance betweenthetop edge of the notch and the top edge of the stay is equal to the depth of the linlc In a slight modification, two stay bars 19 and 20 (see Figures 5 and 6) are pivoted, one on each side of a link 21 pivoted in the bracket 5 as before, and when the bars are in a vertical position the ends 16 of the bars project above the link in the same manner as in Figures 1 and 3. At the'other end of and between these bars 19 and 20 another bar 23 is pivoted upon a pin 24. The end of this bar 23 is shaped in a similar manner to the ends 16 of the other bars and when in its horizontal position rests against a pin 25 so that the bar 23 will only turn in a downward direction. One of the notches 14 would be arranged near to the end 01 the bars 19 and 20, as shown in Figure 5, so that when the stay is placed in position in the bracket in such notch the bar 23 will assume the position shown and the tongue 12 of the lever will: engagewbtween the end 226 land the face of the bracket in the same way as shown in Figure 3 in regard to the first stay.
